Viewing NodeSync Status

View the progress and status of NodeSync operations in OpsCenter Monitoring.

View the progress and status of NodeSync operations for keyspace and tables in OpsCenter Monitoring. The NodeSync Status provides summary and detailed health status.
Tip: The Cluster > Nodes panels also show the cluster summary progress bar. The NodeSync panel status only displays for clusters that are DSE version 6.0 and later.

Prerequisites

Procedure

  1. Click cluster name > Services.
  2. Click the Details link for the NodeSync Service.

    Click the Details link for NodeSync Service to enable keyspaces and tables and view status

    The Status tab displays the current progress of NodeSync operations. The date and time the data was last updated is displayed. The refresh data interval controls the refresh frequency.

    NodeSync Status for keyspaces or tables

    Each cluster, keyspace, and table has a color-coded legend that conveys its NodeSync status (listed from best to worst) when hovering over a particular progress bar:
    • Green: Percentage% of the data was synced within the first 50% of the time period for the NodeSync deadline.
    • Yellow: Percentage% of the data was synced within the first 90% of the time period for the NodeSync deadline.
    • Orange: Percentage% of the data was synced within the last 10% of the time period for the NodeSync deadline.
    • Red: Percentage% of the data was not synced before the NodeSync deadline. An increase in configured throughput is recommended. See Configuring the NodeSync rate using LCM.
    Note: The deadline is a table parameter deadline_target_sec set with an ALTER TABLE statement. Typically, ALTER TABLE t WITH nodesync={ ‘enabled’: ‘true’, ‘deadline_target_sec’ : <some value>}. If the deadline is not explicitly set for a table, the deadline default is whichever is greater: gc_grace_seconds (864000 seconds, which is 10 days) or the maximum gc_grace period (4 hours). For details, see nodesync and gc_grace_seconds table properties.

    When there is not any NodeSync data available for a cluster, a message indicates: NodeSync is enabled but no data is available yet for this cluster. The service may be starting up. Verify in the Settings tab that NodeSync has been enabled for one or more tables. The data refreshes in 5 minute intervals by default.

    No NodeSync data for cluster in Status view

    Be sure to enable keyspace and tables in the Settings tab.

  3. Click the Keyspaces or Tables link to view the Detailed Health Status.
    Tip: Click on a progress bar section to view a tooltip with more details about progress status.
